2005 Pearl White Greddy Turbo RX-8 GT *pics*
People told you a BOV will cause your car to "stumble" because of stuff they have heard on the internets. What happens is incoming air enters through your air filter, then passes over your MAF which measures the air coming in. The air then goes into the compressor housing of your turbo, where a compressor wheel compresses it, the air exits, goes to your intercooler when it is chilled down, and then through your throttle body, winding through your intake manifold, down to some fuel injectors, and finally into your rotor housings where it makes sweet love with gasoline and combustion occurs.
Now, when you let off the gas, say for shifting, that throttle body plate snaps shut, so the air bounces off the plate, and starts going backwards. In your case, without a BOV, the air goes back through the intercooler, and back up into the compressor housing, and against a spinning compressor wheel. That is surge. A blow-off valve opens up so that air doesn't travel all the way back through your cold side plumbing, intercooler, and ultimately surge your compressor and turbine, which is really bad for turbo life.
The "problem" with venting this air the blow-off valve releases to the atmosphere is the MAF has already measured what air is coming in, and given the appropriate fuel meterings required for combustion. So when you vent the air, it looses what the MAF read, so your PCM will meter the wrong amount of fuel.
The good news is the fuel mixture will be rich, so it won't harm your engine. And, it will probably happen when you're off throttle, so you won't notice it, and it only takes a fraction of a second for new air to come back through anyways.
Uh, he answered your questions, didn't he? And you somehow dodged being called an asshat, so consider that a good encounter.

oh, and on topic, the white sleeper look is pretty cool IMO.
$26K Canadian.
That may sound expensive for you guys that live in the US but 2005 RX8's with low mileage are selling for $24-$26k up here. Also I needed to have a white one. There were only a handful of white ones in my area. I had to drive 8hrs away to pick this one up and I pretty much bought it sight unseen.
There were $7500 worth of mods on the car that he recently installed so I save the time to install them all plus the money
